MIDFIELDER Jim Goodwin is struggling to be fit in time for tomorrow’s SPL clash with Hearts at Tynecastle.

The St Mirren skipper has been undergoing treatment for a calf muscle injury he picked up at the tail-end of last week.

However, Goodwin’s injury has not responded as well to treatment as was hoped and he is now rated “doubtful” for tomorrow’s trip to Edinburgh.

Like Goodwin, Saints striker Steven Thompson missed last weekend’s Scottish Cup fourth round game at home to Hamilton Accies.

But it is hoped he’ll be able to shrug off a hamstring string injury and be included in the squad heading for Tynescastle.

Meanwhile, Buddies boss Danny Lennon has revealed he plans to tie Paul McGowan down to a longer contract. The Saints star has been a standout for the Buddies this season but his current deal is due to expire in the summer of 2013.

Lennon said: “Paul is one I’ve spoken to my directors about. He has a year-and-a-half left on his contract and he’s the type of player I want at this club.

“I wouldn’t say that we build our team around one player but the style of football we play complements his ability.”
